I used this a couple of times already, once last week and then again yesterday. I can't believe how well this works. This stuff is amazing! I was worried about my tat yesterday hurting, because it was on my hand and I have boney hands. The only thing I felt was the vibrations from the gun, as far as pain,,,none! Like I said, this stuff is amazing! I have another tat appointment the end of this month so I will be using this again. Thanks!!!!!
